Steel components are manufactured in a controlled factory environment. Cutting, bevel preparation, fit-up, welding, dimensional inspection, and coating operations can be coordinated with the approved drawings and inspection plan.
Prefabricated components can reduce the amount of cutting, welding, and fitting required at the construction site. This approach can help improve erection efficiency and minimize disruption to traffic or surrounding activities.
For export projects, bridge components can be divided into shipping sections according to container dimensions, component weight, lifting limitations, and site assembly requirements.
A project-specific protective coating system can be selected according to the bridge location, environmental exposure, expected maintenance arrangements, and specified coating life.
Depending on the contract, the documentation package can include material certificates, welding inspection reports, NDT records, dimensional inspection reports, coating inspection records, and installation drawings.
- Pedestrian bridges and footbridges
- Landscape bridges in parks and public spaces
- Boardwalk bridges and recreational crossings
- Small road bridges using steel box girders
- Steel truss bridges for light-duty infrastructure applications
Bridge fabrication requires close control of material traceability, weld preparation, dimensional accuracy, welding quality, and corrosion protection.
Depending on the approved drawings and inspection plan, our fabrication scope can include:
- Bridge-grade steel plate cutting and bevel preparation
- Component fit-up and welding in accordance with approved welding procedures
- Visual inspection and specified non-destructive testing (NDT)
- Dimensional inspection before shipment
- Surface preparation and application of the specified heavy-duty protective coating system
- Component marking, shipment planning, and preparation of quality records
Inspection methods, acceptance criteria, and testing coverage are defined by the project specifications and applicable standards. Where required, inspection reports and material documentation can be compiled into a project handover package.
Bridge Fabrication Workshop
Steel bridge components can be fabricated in transportable sections according to container dimensions, component weights, shipping restrictions, and site assembly requirements.
To support overseas project coordination, we can provide fabrication drawings, component marking schedules, assembly details, and English-language installation documentation according to the agreed scope. Remote technical support can help contractors understand component identification, connection details, and the planned assembly sequence.
Shipping arrangements and installation procedures are reviewed against the specific project conditions, including lifting equipment, site access, and erection requirements.
Our steel bridge fabrication services cover steel box girders, steel trusses, and steel arch components for pedestrian bridges, landscape bridges, boardwalks, and small road bridge projects.
We coordinate fabrication planning with approved structural drawings, material specifications, welding details, dimensional tolerances, and transportation requirements. Manufacturing processes may include steel plate cutting, bevel machining, component fit-up, welding, dimensional inspection, and protective coating.
For overseas projects, component segmentation and connection details are also considered during fabrication planning to facilitate transportation, handling, and on-site assembly.
We manufacture steel bridges for pedestrian crossings, landscape projects, boardwalks, and small road bridges. Available structures include steel box girders, steel trusses, and steel arches.
